Certified Guaranty Company

Certified Guaranty Company (CGC) is an independent member of the Certified Collectibles Group (CCG). Upon its founding in 2000, CGC became the world's first and only independent, impartial, third-party comic book grading service. More than two million comic books later, CGC is the leader in its field, recognized and respected for its commitment to integrity, accuracy, consistency and impartiality.

CGC certification offers many benefits to comic book collectors. Every comic book certified by CGC is graded by the hobby's most experienced and trusted team, according to well-established grading standards. It's then encapsulated in a state-of-the-art, tamper-evident holder, providing superior protection and stability for long-term preservation.

Because we value our relationship with collectors who share our passion for comics, the hobby's vibrant history and its exciting future, we offer membership in the CGC Collectors Society. All members can participate in the Comics Registry, and Associate or higher-level members can submit comics directly to CGC for certification and encapsulation.
